Build Chamber Hyperbaric
The relatively new medical tool offers an inexpensive alternative to the solid, room-like constructions found in some hospitals. These similarly administer oxygen at higher concentration levels than ordinary air normally provides to stimulate wound healing. Such facilities are expensive to build, with capital costs of approximately $1 million, and are costly to maintain. They require extensive cleaning after each use, and require total immersion of the patient in the oxygen-enriched chamber. Costs for an oxygen treatment in such facilities can reach $1,500, while the Numobag’s estimated cost per treatment is $185, according to figures provided by MR Beal Inc., a New York-based investment house providing backing for the venture.
Dr. Glen Heywood, a professor of surgery at the Health Sciences Center at the University of New Mexico, says that he is “gearing up to try the Numobag for the most serious wound infections we deal with as surgeons — necrotizing fasciitis. There have been studies — some conflicting — but the studies seem to support that topical hyperbaric oxygen therapy may be helpful. We have in New Mexico one of the highest amounts of necrotizing fasciitis, maybe because our oxygen content is lower because of our higher altitude. We are the closest clinical institution in closest proximity to Sandia, where a significant portion of the engineering research has been done. Most of the clinicians are located in California. So it seemed appropriate for us to be a test site for the technique. Our aim is to achieve an objective randomized evaluation; it’s important that we clearly compare the efficacy of the Numobag with other techniques to find which wounds this technique operates on most effectively.
